The police, led by Inspector Bejoy, intercept a van transporting 900 kilograms of cocaine valued at over ₹800 crores. They keep the narcotics and those involved at the commissioner's office. The bust threatens the operations of Adaikalam, a notorious drug lord based in Trichy, whose identity remains unknown to the authorities. In retribution, his brother Anbu plots to retrieve the seized drugs and eliminate the officers responsible.
During a retirement party for the Inspector General, the city's senior police officers are drugged by mixing Rohypnol with alcohol rendering them unconscious. Bejoy, who abstains due to medication, remains unaffected. To prevent public panic, he attempts to move the officers covertly to a hospital. He enlists the help of Dilli, a recently released prisoner detained for suspicious behaviour, by leveraging his desire to reunite with his daughter, Amudha, who is waiting at an orphanage. Kamatchi, a caterer at the party, aids them, and they use his truck to transport the incapacitated officers. Meanwhile, Anbu places a bounty on the police officers, prompting gang members to pursue the group. Paalpandi, a corrupt officer pretending to be unconscious, helps them.
At the commissioner's office, Bejoy instructs Constable Napoleon and a group of college students detained for drunk driving to secure the premises and prevent Anbu's men from accessing the building or freeing the detainees. En route, Dilli defends the group against multiple gang attacks.
Bejoy later learns that Adaikalam himself is among the captured smugglers. Although Bejoy momentarily negotiates a deal between Napoleon and Anbu for a prisoner exchange, he cancels it upon this discovery. Anbu infiltrates the commissioner's office, but the students subdue him. As Dilli, Kamatchi, and Bejoy near the office after getting the unconscious officers to a hospital, a gang, led by Anbu's lieutenant, Tips, ambushes them. Paalpandi, pretending to have recovered, stabs Dilli, and Bejoy is overpowered. Ajaz Ahmed, Bejoy's informant inside Anbu's gang, is killed by Tips. Dilli recovers and defeats the attackers, rescues Bejoy and Kamatchi, and kills Tips and Paalpandi.
Back at the commissioner's office, Anbu orders the execution of one of the students, prompting Napoleon to subdue him with a fire extinguisher. Adaikalam, witnessing this, vows revenge. Dilli enters the building through a hidden passage and helps the students escape. Subsequently, he and Napoleon set out to destroy the narcotics. They find a confiscated M134 minigun and use it to eliminate Anbu's forces. A doctor revives the unconscious officers, and Stephen Raj, the corrupt Zonal Head of the Narcotics Division, is arrested for his involvement in Anbu's plot.
Bejoy thanks Dilli and promises him a better life. Dilli is reunited with Amudha, brought by his probation officer, Nalini. In the final scene, as Dilli, Amudha, and Kamatchi walk away toward a new life, Adaikalam, from his prison cell, implies that he knows Dilli personally.
